Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention divides a frame or a frame of a fitting into an indoor side member and an outdoor side member made of an extruded shape member, and heat-insulates caulking holes formed respectively on opposing surfaces of these members. The present invention relates to a heat-insulating profile obtained by internally fitting both ends of a bridge material and crimping.

[0002]

2. Description of the Related Art In fittings such as windows and doors used in cold regions, heat is prevented from being taken out of the room through a frame or a frame made of an extruded aluminum alloy having good heat conductivity. As illustrated in FIG. 4 for the corners of the shoji screen, the vertical frame 1 and the horizontal frame 2 are divided into indoor side members 1a, 2a and outdoor side members 1b, 2b made of extruded shape members,
Bridge members 5 and 6 made of a heat insulating synthetic resin or the like are provided in the caulking holes 3 and 4 respectively formed on the facing surfaces of these members.
Both ends of are fitted and crimped.

Such a heat-insulating profile has airtight material holding pieces 7 and 8 at both ends of one frame (vertical frame 1 in the illustrated example) (the airtight material holding pieces 7 and 8 are as shown in FIG. 1). , The panel 9 and the frames 1 and 2 are fitted with an airtight material 10 for maintaining the airtightness), and the other frame (the horizontal frame 2 in the illustrated example)
A structure is adopted in which the cutting part is fitted into the cutout part and is coupled with a screw (not shown). When such a structure is adopted, as shown in FIG. 5, the caulking holes 3 and 4 have bridge members 5,
6 (vertical and horizontal bridge members 5, 6 may be provided one each instead of two as shown)
Of the bridge members 5 and 6 by deforming the caulking pieces 3a and 4a by sandwiching the both ends with the rollers 11 and 12 and pressing the caulking pieces 3a and 4a from both sides while pulling out the shape member. Crimp the ends of the
Indoor and outdoor members 1a and 1b, 2a and 2b of the frames 1 and 2 are joined to form a vertical frame 1 and a horizontal frame 2.

[0004]

However, according to this caulking structure, as shown in FIG.
When the caulking pieces 3a, 4a are pressed by means of 1, 12 and the bridge members 5, 6 are caulked, the airtight material holding piece 7 interferes with the roller 11 so that the tips of the caulking pieces 3a, 4a are more than the airtight material holding piece 7. Also has to be projected so as to cause a difference in projection height indicated by h, and in order not to deteriorate the appearance, the back surface a of the surface where the caulking hole 3 is formed and the surface where the airtight material holding piece 7 is formed are formed. Although it is necessary to form a flat boundary with the back surface b, the horizontal frame 2 is swallowed in the vertical frame 1, and the bridge member 5 used for the vertical frame 1 and the bridge member 6 used for the horizontal frame 2 are W. Since it is preferable to use the same material having the same width, the thickness d of the caulking hole 3 forming portion of the outdoor side member 1a of the vertical frame 1 is much larger than the thickness e of the airtight material holding piece 7 forming portion. Become.

Therefore, firstly, when the outdoor member 1a is extruded, a molten aluminum alloy preferentially flows into a portion having a large thickness indicated by d, so that a portion outside the intended size range is formed. Secondly, there is a problem that the yield is deteriorated. Secondly, as shown in FIG. 5, due to the easiness of the flow of the aluminum alloy in the step portion between the thick portion having the thickness d and the thin portion having the thickness e, the aluminum alloy Is locally pulled down, and as a result, a streak-shaped concave portion f is formed, and it may appear to be broken due to the reflection of light, or may actually be broken. Thirdly, aluminum Due to the temperature difference during extrusion of the alloy, the surface a of the thick portion and the surface b of the thin portion
There is a problem in that the colors look different (they are the same silver color, but one looks blackish and the other looks whitish).

In view of the above problems, the present invention reduces the yield due to the drift of the material generated during the extrusion process due to the difference in wall thickness between the bottom portion of the caulking hole of the bridge material and other portions, Another object of the present invention is to provide a heat insulating profile having a structure capable of preventing the deterioration of the appearance and saving the material.

[0007]

In order to achieve the above-mentioned object, the present invention divides a frame or a frame of a fitting into an indoor member and an outdoor member made of an aluminum alloy extruded shape member, and The both ends of the heat insulating bridge material are fitted into the caulking holes between the caulking pieces respectively formed on the opposite surface parts by caulking, and the projecting portion adjacent to the caulking piece and projecting in the same direction as the caulking piece is provided in the chamber. It is provided in at least one of the inner member and the outdoor member, and the boundary between the rear surface of the protruding portion forming surface and the rear surface of the caulking hole forming surface is formed flat, and the protruding portion of the protruding portion protrudes the caulking piece. It is characterized in that the height is increased, the thickness of the bottom surface of the caulking hole is made thicker than the thickness other than the bottom surface, and a groove for thinning is provided on the bottom surface of the caulking hole. In the shoji, one end of the vertical and horizontal frames is swung into the other end and connected, and the widths of the bridge members interposed between the vertical and horizontal indoor side members are made equal, and the caulking is performed. The airtight material holding piece is provided as a protruding portion adjacent to the piece and protruding in the same direction as the caulking piece.

[0008]

As described above, according to the present invention, since the groove for thinning is provided on the bottom surface of the caulking hole, uneven flow of the profile material at the time of extrusion molding is prevented, resulting in poor appearance and breakage. ,
Color difference does not occur, and less material is required for forming the groove.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a cross sectional view showing a case where an embodiment of the heat insulating profile according to the present invention is applied to a tumbling window, FIG. 2 is a vertical cross sectional view thereof, and FIG. is there. 1 to 3, reference numeral 20 denotes a shoji which is composed of the left and right vertical frames 1, upper and lower horizontal frames 2 and a panel 9. The vertical frame 1 and the horizontal frame 2 of the shoji 20 are respectively as described above. The outdoor side members 1a and 2a are made of extruded aluminum alloy, the indoor side members 1b and 2b, and the bridge members 5 and 6 between them.

Reference numeral 21 is a frame composed of left and right vertical frames 22 and upper and lower horizontal frames 23, and the vertical frames 22 and the horizontal frames 23 are outdoor members 22a and 23a made of aluminum alloy extruded profiles, respectively. The indoor side members 22b and 23b and the bridge members 24 and 25 between them are formed.

As shown in FIG. 2, the shoji 20 has an R-shaped fulcrum portion 26 formed on the indoor side member 23b of the lower horizontal frame 23.
By engaging the R-shaped pivoting portion 27 formed on the indoor side member 2b of the horizontal frame 2 on the lower side of the shoji 21 with this, it becomes possible to rotate so as to incline to the indoor side as indicated by the arrow r. And
When the link 19 interposed between the vertical frame 22 and the vertical frame 1 extends to the maximum extent, the opening angle is restricted so that the shoji 20 cannot be opened any further. 29 is a lock claw provided on the upper part of the shoji 20 and 30 is a lock claw 2 provided on the upper horizontal frame 23.
9 is a locking metal fitting, 31 is an airtight material attached to the window frame 21 so as to abut the frame of the shoji 20, and 32 is a screen door.

The present invention is a fitting having a structure in which the ends of a frame or a frame are cut at an angle of, for example, 45 degrees and abutted against each other, and an L-shaped coupling fitting is provided at the abutting portion to be coupled with a screw or the like. In this embodiment, as shown in FIGS. 1 and 3, the vertical frame 1 of the shoji 20 has a structure in which the horizontal frame 2 is swallowed. While the width in the direction becomes wide, the bridge members 5, 6 in the vertical and horizontal directions
Since the same type having the same width W is used, the thickness d of the bottom surface portion of the caulking hole 3 provided in the outdoor side member 1a of the vertical frame 1 is set to be larger than the thickness e of the forming surface of the airtight material holding piece 7. There is. In the present embodiment, a groove 13 for thinning is provided on the bottom surface of the caulking hole 3.

By providing the groove 13 as described above, the bottom portion of the caulking hole 3 is thinned as a whole, and the aluminum alloy in a molten state is preferentially applied to a portion having a large thickness when the outdoor side member 1a is extruded. It prevents the occurrence of the phenomenon of flowing and squeezing of the dimension, and prevents the occurrence of streak-like recesses in the step of the thickness so that it will not be broken or appear to be broken on the appearance. Due to the temperature difference during the extrusion of the aluminum alloy on the surface b of the portion, the color of the material does not look different. Further, in order to eliminate the difference in wall thickness, if a step is provided at the boundary between the back surface a of the caulking hole forming surface of the outdoor side member 1a and the back surface b of the forming surface of the airtight material holding piece 7, the appearance is deteriorated, Although the merchandise value is reduced, in the present embodiment, since the boundary portion is formed flat, such a problem does not occur.

The wall thickness e of the thin portion where the airtight material holding piece 7 is formed is generally set to about 0.8 mm to 1.2 mm, and the wall thickness d of the bottom portion of the caulking hole 3 is 3.5 mm to 5.0 mm. The thickness j of the portion where the groove 13 is provided is
In order to prevent the bending of the groove 13 at the time of caulking, 1.2 mm or more of the thickness e of the thin portion
It is preferable to set it to about 2.0 mm. Further, the caulking piece 3a projects from the airtight material holding piece 7 with a height difference shown by h, as described in the above-mentioned conventional example. The height difference h is about 2.5 mm to 4.0 mm. It is preferable to set.

Thus, the groove 13 is formed at the bottom of the caulking hole 3.
The structure for providing the frame 2 does not have to be provided only for the shoji 20 and the frame 2
It may be provided on the first side. When the structure of the present invention is applied to the frame 21, the protrusions such as ribs are provided on the vertical frame 22 or the horizontal frame 23, so that the protrusions interfere with the insertion of the rolls 11 and 12. In this case, if the boundary between the back surface of the rib forming surface and the back surface of the caulking hole forming surface is made flat in view of the appearance and the like, the bottom thickness of the caulking hole is inevitably increased. ,
By providing the groove for thinning the bottom of the caulking hole of the bridge member 24, it is possible to suppress the occurrence of defects caused by the difference in wall thickness.

In addition to the above-described embodiment, the present invention also provides a groove 1
It is possible to make various changes such as providing a plurality of three lines, and the structure and combination of the frame, the frame, the bridge member, the caulking hole, the groove at the bottom of the caulking hole, the protruding portion, etc. within the scope of the present invention. Various changes and additions are possible. In the present invention, the boundary between the rear surface of the caulking hole forming surface having the thinning groove and the rear surface of the protruding portion forming surface is
It may be flat as long as it does not substantially impair the appearance.

[0017]

According to the first aspect of the present invention, in a heat-insulating profile obtained by interposing a heat-insulating bridge material between the outdoor member and the indoor member, a groove for thinning is provided at the bottom of the caulking hole. Since it is provided, the boundary between the back surface of the caulking hole and the back surface of the caulking hole is formed to be flat to maintain a good appearance, and the difference in wall thickness between the caulking hole bottom surface and other parts is reduced. As a result, defective appearance, breakage, and color difference do not occur due to uneven flow of material during extrusion molding, and a decrease in yield can be prevented. Further, since the groove is provided at the bottom of the caulking hole, the material cost can be saved, and as a result, the manufacturing cost can be reduced together with the improvement of the yield.

According to the second aspect, since it is not necessary to use vertical and horizontal bridge materials having different widths in order to improve the appearance, the material cost is low, and the manufacturing complexity is not required.
